Rihanna’s friends and music industry peers — including Jay-Z — are telling her she needs to check into rehab following a number of alarming incidents in recent months indicating the singer’s life in the fast lane is eroding her gorgeous looks and impacting her work.

“Rihanna has been out of control for months,” an insider told Closer magazine. “She was supposed to catch a flight back to the UK last week [for a work obligation], but she ended up missing it, which was the final straw for management. Jay-Z hit the roof when he found out, and told Rihanna, ‘Go to rehab now or I’ll drop you from the label.’ “She’s not happy, but she now feels she has no choice.”
